  • Title: [Right ventricle--pulmonary artery diastolic blood flow (author's transl)].
    Author: Maciel RE, Bittencourt LA, Carvalhal SD, De Paiva CE.
    Journal: Rev Bras Pesqui Med Biol; 1976; 9(1):7-11. PubMed ID: 935566.
    Abstract:
    The authors show the possibility of the establishment of blood flow from the right ventricle to the pulmonary artery during the period of ventricular diastole, through experimental models mimetizing hemodynamic patterns described in the literature for certain cardiopathies. These models consisted of experimental hypodiastoly, associated or not with right ventricle hyposystoly. The detection of the existence or not of blood flow in the several phases of the cardiac cycle, was made recording the variations of the electrical impedance of the blood.
